Long spiral optical waveguides using ultra low loss perfluorinated polymer for optical interconnect

Multimode polymer optical waveguides with long spiral path using a perfluoropolymer are demonstrated. Spiral path length is 1.254 m and NA is 0.26. Propagation loss at 1310, 1550, and 1650 nm were 0.047 dB/cm, 0.049 dB/cm, 0.070 dB/cm , respectively.
